Technical Field

[0001] The invention relates to the technical field of kitchen electrical appliances, in particular to an adaptive cooker and a working method thereof. Background Art

[0002] Cookers are heating appliances used for cooking in the kitchen. The mainstream cookers on the market are gas stoves and induction cookers. Gas stoves heat the bottom of the pot by burning gas. Induction cookers heat the pot by generating eddy currents at the bottom of the pot through electromagnetic induction, which heats the pot.

[0003] However, existing gas stoves and induction cookers all have their limitations.

[0004] The gas stove has a fixed hob, which cannot be adapted to different pots and pans, which may cause the pots and pans to be placed unstable. The size of the fire ring is relatively fixed, and the heating point is limited to a smaller part of the bottom of the pot. It cannot adapt to the firepower in a larger range and is difficult to meet a variety of cooking needs. At the same time, due to the existence of the hob, the gas stove affects the integrity of the kitchen countertop.

[0005] However, induction cookers have certain requirements on the material and shape of cookware. They can only use flat pans and cannot stably place and heat curved bottom pans. Summary of the invention

[0006] In view of the problems existing in the prior art, the purpose of the present invention is to provide an adaptive cooker and a working method thereof, which can adapt to different pots and pans, the pots and pans can be placed stably, and the firepower can be adapted within a larger range to meet various cooking needs.

[0007] In order to achieve the above object, the present invention adopts the following technical solution: An adaptive cooker comprises a control device, a detection device and a cooker panel for placing a pot; The cooker panel includes a base and a plurality of lifting units arranged in an array on the base; Each lifting unit includes a driving device, a furnace frame and a heating device; The driving device and the heating device are both fixed to the base, and the furnace frame is sleeved outside the heating device and flush with the heating device; the driving device is respectively connected to the furnace frame and the control device, and is used to drive the furnace frame to move up and down on the base under the control of the control device to form a pot support; The detection device is arranged corresponding to the cooker panel, and is used to detect the shape and position data of the pot placed on the cooker panel and send the data to the control device; The control device includes an automatic part, which is used to select multiple lifting units from the cooker panel as pot supports according to the shape and position data of the pot and control the heating devices of the multiple lifting units within the pot support range to heat the pot.

[0008] Furthermore, the heating device is a gas-fired heating device and / or an electric heating device. The gas-fired heating device includes a fire cover, a gas channel and a valve controller. The fire cover is arranged in the furnace frame. An ignition device is provided on one side of the fire cover. The valve controller is connected to the gas channel. The valve sleeve of the valve controller is provided with a first return spring. The valve is used to control the connection between the fire cover and the gas channel. The control device is respectively connected to the ignition device and the valve controller. The electric heating device is an induction coil.

[0009] Furthermore, the control device also includes a manual part, which includes a main switch, a display panel, a fire power knob and a guide rail arranged on one side of the stove panel. The main switch is used to control the start of the stove panel, the display panel is used to display stove information, heating method and fire power status, and the fire power knob is slidably connected to the guide rail.

[0010] Furthermore, a contact pin is connected to the bottom of the fire knob, and when the contact pin of the fire knob is fully inserted into the guide rail, the stove panel is ventilated.

[0011] Furthermore, the guide rail is provided with a plurality of fixed points at intervals along the axial direction, each fixed point is provided with a fire power adjustment male contact and a gas connection male contact, the contact pin is provided with corresponding fire power adjustment female contacts and gas connection female contacts, second return springs are respectively provided at both ends of the guide rail, the second return springs are sleeved with a first pressure sensor, and a second pressure sensor is provided at the bottom of each fixed point.

[0012] Furthermore, when the fire knob is inserted into the fixed point of the guide rail, the valve controller is connected, the fire knob is rotated to control the opening degree of the valve, and the fire knob is pressed to switch between the gas and electric heating modes; when the fire knob slides to the two ends of the guide rail, the pot selection operation is switched to the left or right; when the fire knob is pulled out, the gas connection male contact and the gas connection female contact are disconnected, the valve of the valve controller is automatically closed, and the gas channel is disconnected.

[0013] Furthermore, the lifting unit is circular or polygonal.

[0014] A method for operating an adaptive cooker comprises the following steps: Obtaining shape and position data of the pot placed on the cooker panel; According to the shape and position data of the cookware, multiple lifting units at corresponding positions are selected from the cooker panel as cookware supports, and the heating devices of the multiple lifting units within the cookware support range are controlled to heat the cookware.

[0015] Furthermore, when the heating device is a gas-type heating device, the grate selected as the lifting unit for supporting the pot rises more, and a gap is left between the gas-type heating device within the supporting range of the pot and the bottom of the pot; when the heating device is an electric-type heating device, the grate selected as the lifting unit for supporting the pot rises less, and the electric-type heating device within the supporting range of the pot directly performs contact heating on the bottom of the pot.

[0016] Furthermore, when the heating point needs to cover more or less of the bottom of the pot, a plurality of lifting units corresponding to the outer edge of the pot shrinking less or more inwardly are selected as pot supports.

DETAILED DESCRIPTION

[0035] The present invention will be described in further detail below.

[0036] like Figure 1 , Figure 2 As shown, an adaptive cooker comprises a detection device 1, a control device and a cooker panel 2 for placing pots.

[0037] The cooker panel 2 includes a base and a plurality of modular lifting units 8 arranged in an array on the base. The cooker panel 2 is embedded on the kitchen countertop 3 , and the base is fixedly connected to the kitchen countertop 3 .

[0038] The control device includes an automatic part and a manual part. The manual part includes a fire knob 4, a main switch 5, a guide rail 6, and a display panel 7, which are distributed on one side of the stove panel 2.

[0039] When the cooking function of the stove panel 2 is not used, the upper end surface of the stove panel 2 is flush with the kitchen countertop 3, and the degree of integration with the kitchen countertop 3 is high, which can keep the kitchen countertop 3 flat and beautiful, and increase the use area of ​​the kitchen countertop 3; like Figure 7 , Figure 8 As shown, the lifting unit 8 can be in various shapes such as circular or polygonal to meet the personalized needs of users.

[0040] like Figure 3 , Figure 4 As shown, each lifting unit 8 includes a driving device, a furnace frame 11 and a heating device; the heating device can be an electric heating device and / or a gas heating device, the electric heating device can be an electric heating wire, and the driving device can be a micro motor 17.

[0041] The driving device and the heating device are both fixed to the base; the furnace frame 11 is sleeved outside the heating device and is flush with or slightly higher than the heating device, so as to protect the heating device; the driving device is respectively connected to the furnace frame 11 and the control device, and is used to drive the furnace frame 11 to move up and down on the base under the control of the control device to form a pot support; The detection device 1 is arranged corresponding to the cooker panel 2, and may be a camera arranged on the smoke extractor, and is used to detect the shape and position data of the pot placed on the cooker panel 2 and send the shape data to the control device, wherein the shape data includes the shape contour, depth, width, etc. of the pot, and the position data includes the position of the pot on the cooker panel 2, etc.; The control device automatically selects a plurality of lifting units 8 from the cooker panel 2 as the cooker support according to the shape data of the cooker, and controls the heating devices of the plurality of lifting units 8 within the cooker support range to heat the cooker through the control device.

[0042] When in use, first turn on the main switch 5, start the electrical part of the cooker panel 2, then place the pot on the cooker panel 2, the detection device 1 automatically detects the shape and position of the pot and sends the detected data to the control device, and the control device selects multiple lifting units 8 from the cooker panel 2 as pot supports according to the received pot data, and executes the heating function of the multiple lifting units 8 within the pot support range according to the control method.

[0043] The multiple lifting units 8 selected as the pot support can adapt to the shape of the pot to keep the pot stable. The pot support range can be obtained by shrinking the outer edge of the pot inward by a preset distance, but is not limited to this.

[0044] For example, when the pot is placed on the cooker panel 2, the plurality of lifting units 8 corresponding to the circle of the pot outer edge slightly contracted inward can be selected as the pot support, and the plurality of lifting units 8 can be distributed in a regular polygon, such as 3 lifting units 8 distributed in a regular triangle, 4 lifting units 8 distributed in a square, 6 lifting units 8 distributed in a honeycomb shape, etc. The driving device drives the hob 11 of these lifting units 8 to rise a certain height from the base, and the heating devices of other lifting units 8 within the pot support range will be activated and heat the pot together. In this case, the area within the pot support range is larger, the heating devices included are more, the heating points cover a larger part of the bottom of the pot, the heating speed is higher, the pot surface is heated faster, the heating is more uniform, the cooking efficiency is improved, and it is particularly suitable for large-capacity and fast-speed cooking; if the pot is small, the corresponding plurality of lifting units 8 are selected as the pot support, the area within the pot support range is smaller (the size of the minimum range can refer to the relative size of the fixed hob 11 in the prior art), the heating devices included are fewer, the heating speed is lower, and it is particularly suitable for small-capacity and slow-speed cooking.

[0045] The multiple lifting units 8 of the stove panel 2 of the present invention can be adaptively lifted and lowered according to different pots to form pot supports of different ranges, and can adapt to different pots, whether the pots are curved bottom pots or flat pans. The pots are stably placed and can be heated within different pot support ranges. The number of heating devices changes with the change of the pot support range, and the firepower can be adapted within a larger range to meet various firepower cooking needs.

[0046] like Figure 2 , Figure 5 , Figure 6 As shown, the gas-fired heating device comprises a fire cover 10, a gas channel 12 and a valve controller 13. The fire cover 10 is arranged in a furnace frame 11. An ignition device 9 is arranged on one side of the fire cover 10. The valve controller 13 is connected to the gas channel 12 and is used to control the connection between the fire cover 10 and the gas channel 12. The control device is connected to the ignition device 9 and the valve controller 13 respectively. A valve 15 is arranged on the gas channel 12. The valve controller 13 is connected to the valve 15 and is used to control the valve 15 to open the gas channel 12. The valve 15 is sleeved with a first return spring 16.

[0047] When the gas-fired heating device is selected for heating, the valve controller 13 activates the valve 15, so that the valve 15 opens the gas passage 12, and the gas enters the fire cover 10 from the gas passage 12, and the ignition device 9 on one side of the fire cover 10 is ignited, and the gas burns through the fire cover opening 14. When the heating is finished, the valve 15 blocks the gas passage 12 again under the action of the first return spring 16.

[0048] The electric heating device includes an induction coil 18, and a fire cover 10 is provided below the induction coil 18. When the electric heating device is selected for heating, the induction coil 18 located on the top of each fire cover 10 will be powered on and generate heat.

[0049] In this embodiment, the ignition device 9 is disposed in the middle of three adjacent lifting units 8, and can ignite three surrounding fire covers 10 at the same time, thereby improving work efficiency.

[0050] This embodiment also provides a working method of an adaptive cooker, comprising the following steps: Acquire the shape and position data of the pot placed on the cooker panel 2; According to the shape and position data of the cooker, a plurality of lifting units 8 are correspondingly selected from the cooker panel 2 as the cooker support, and the heating devices of the plurality of lifting units 8 within the cooker support range are controlled to perform heating.

[0051] When the heating point needs to cover more of the bottom of the pot, multiple lifting units 8 corresponding to the outer edge of the pot shrinking less inward are selected as pot supports; when the heating point needs to cover less of the bottom of the pot, multiple lifting units 8 corresponding to the outer edge of the pot shrinking more inward are selected as pot supports.

[0052] When the heating device is a gas-fired heating device, a gap is left between the gas-fired heating device within the support range of the pot and the bottom of the pot, providing space for oxygen to enter, ensuring that the gas can be fully burned and achieving good heating efficiency; when the heating device is an electric-heating device, the furnace rack 11 of the multiple lifting units 8 selected as the pot support rises less, and the electric-heating device within the support range of the pot directly performs contact heating on the bottom of the pot to reduce heat loss.

[0053] like Fig. 9 As shown, there is an indicator light 19 on the top of the fire knob 4, and a contact pin 20 is connected to the bottom of the fire knob 4. The contact pin 20 has two grooves, the upper groove is a fire adjustment female contact 21, and the lower groove is a gas connection female contact 22.

[0054] As shown in Figure 10 (a), Figure 10 (b), Fig.11 , Fig.12 As shown, the guide rail 6 contains a fire adjustment male contact 26, a gas connection male contact 27, a second reset spring 25, a first pressure sensor 23 and a second pressure sensor 28; the guide rail 6 is provided with four fixed points 24 at intervals along the axial direction, and the fire adjustment male contact 26 is distributed in a small arc at the four fixed points 24 of the inner wall of the guide rail 6; the gas connection contact 27 is distributed in a strip shape on the inner wall of the guide rail 6; the second reset spring 25 is combined with the first pressure sensor 23, and is distributed on both sides of the inner wall of the guide rail 6; the second pressure sensor 28 is located at the bottom of the four fixed points 24 of the guide rail 6.

[0055] As shown in Fig. 13 (a) and Fig. 13 (b), when the pot is placed on the cooker panel 2, the order of the pot placement and the corresponding icons on the display panel 7 follows the following rule: the pot that is on the upper left has the icon on the left side of the display panel 7, and vice versa. The icon is on the right side of the display panel 7. The manual control method of the control device is that the fire knob 4 can control the fire power and switch the heating mode when it is at the four fixed points 24 of the guide rail 6, and the pot displayed on the display panel 7 can be switched when it slides to the two ends of the guide rail 6.

[0056] When in use, when the contact pin 20 of the fire knob 4 is completely inserted into the guide rail 6, the fire knob 4 is at any position of the guide rail 6, the gas connection female contact 22 is always in contact with the gas connection male contact 27, the gas on the cooker panel 2 is connected, and the indicator light 19 of the fire knob 4 lights up; When the contact pin 20 of the fire power knob 4 slides to the position of any one of the four fixed points 24 in the guide rail 6, the fire power adjustment female contact 21 and the fire power adjustment male contact 26 are in contact, and the rotation of the fire power knob 4 can control the opening degree of the valve 15 of the valve controller 13, so as to achieve the purpose of adjusting the fire power. The fire power knob 4 presses the second pressure sensor 28 at the bottom of the guide rail 6 to receive the pressure signal, and the heating mode of the current cookware can be switched to electric heating or gas heating; when the fire power knob 4 slides to the left and right ends of the guide rail 6, the second return spring 25 will be squeezed, and the corresponding display panel 7 will perform the left and right switching operation. The first pressure sensor 23 has different switching speeds according to the elastic force of the second return spring 25. The greater the elastic force, the faster the switching speed; when the fire power knob 4 is pulled out of the guide rail 6, the gas connection male contact 27 and the gas connection female contact 22 are disconnected, and the valve 15 of the valve controller 13 is automatically closed.

[0057] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
